PUMP.`

SPECIFICATION forming part ofl Letters Patent No. 678,009, dated July 9, 1901.

Application led October 9, 1900. Serial No. 32,498. (No model.)

To LM whom, t may concern:

Be it known that I, WILLIAM S. MCLEOD, a subject of the Queen of Great Britain, residing in Kingsville, in the county of Essex and Province of Ontario, Canada, have invented new and useful Improvements in Pumps, of which the following isa specilication.

This invention relates to pumps, and more particularly to a pump-plunger; and the primary object thereof is toI so construct the plunger that the eiciency of the valve thereof will be maintained by action of the fluid passing through the plunger.

A further object is to provide a non-corrosive plunger of simple and improved construction.

The invention consists in the novel features of construction and inthe combination and arrangement of parts hereinafter fully described and claimed, and illustrated by the accompanying drawings, in which- Figure 1 is a vertical sectional view of the lower portion of a pump embodying my improvements. Fig. 2 is an elevation, partly in section, of the upper portion of the same.

Referring to the drawings, 2 indicates the cylinder, which is seated in the upper and lower cylinder-heads 3 and 4, respectively, the heads being secured together by two verticalclampingfrods 5. Induction-pipe 6 and eduction-pipe 7 unite at their lower ends with heads 8 and at their upper ends with heads 9, and these heads are of a size to unite with cylinder-heads 3 and 4,A being clamped together with the cylinder-heads therebetween by the four clamping-rods 10. Interposed between the faced ends of the heads are projecting edges 11 of partition-plates l2. Each plate is formed with the oppositely-projecting and continuous ange 13, fitting within the united heads, and thus making tight joints when the heads and interposed partitionplates are united by rods 10. Each plate 12 has an orifice 14, surrounded by valve-seat 15. Ears project from each plate 12, and hinged therebetween on pin 18 is pallet 19, which projects above the pin to form stops 20,which bear against plate 12 and limit the throw of the pallet. The lower extremity of the latter is apertured to receive the stem of valve' disk 22, the parts being united by screw 23. The plunger is formed of two glass or metal disks 26, apertured vertically at 27 and sei cured on stem 28, being provided with leather orotherpacking-cups29. Immediatelyabove the plunger-head the stem is enlarged at 30 and spirally grooved at 3l, and operative thereon is glass valve-disk 32. Water passing upward through grooves 31 causes disk 32 to rotate, thus keeping the plunger clear of sand or other sediment, which otherwise would collect on-the plungeraround the stem and impair the eficiency of thevalve.v The glass disks formingthe valve and plunger are easily molded and are non-corrosive, being unaffected by impurities in the water which attack plungers formed of iron.

The valve-stem unites with plunger-rod 33, and carried thereby ispiston 34, formed of suitable packing material, which works in cylinder 35, the latter uniting with cylinderhead 3. I iind this arrangement far superior to the universally-used stuffing-box, as it is easier to keep tight, and the rod is not Acut or roughened, as with an ordinary stuffing-box.

Eduction-pipe 7 extends to air-chamber 36, from which the water may discharge through spout 37 or through a pipe (not shown) lead ing to a distant point. Cast integral with the air-chamber are horizontal guides or brackets 38 forV the upper end of plunger-rod 33, the lower bracket also forming a fulcrum for link 38' of handle 39. Thus a permanent vertical guideway is provided for the rod without introducing separate castings, as heretofore, thereby reducing the number of parts and avoiding the expense incident to fitting such parts together.

' Eduction-head 9 is fitted With drain-cock 40, adaptedto be manipulated from above iioor 41 by stem 42. Induction-head 9 may be tted with pipe 43, which forms an air-chamber for that side of the pump. Water may enter` the pump through any one of inlet-openings 44,01- said openings may have valved connections -(not shown) with as many diiferent sources of supply, from any one of which the water may be drawn. Instead of discharging from the top the water may be discharged from either of apertures 45 in the lower eduction-head 8.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is=a 1. The combination of a vertically-apertured plunger, a vertically-movable and revoluble valve coperating therewith, and a Vertical guide for the valve (formed with spiral grooves on its guiding-face, whereby water coursing through the said grooves causes the valve to rotate, substantially as shown and described. v

2. An improvement in pumps, comprising a verticaliy-apertured plunger, a plungerstem spirally grooved immediately abovethe plunger, and a valve-disk movable vertically on said grooved portion of the stem and adapted to be rotated thereon by the action of the water passing through the grooves, substantially as shown and described.

3. An improvement in pumps, comprising a vertically-apertured plunger, a stem, said plunger consisting of two glass disks and two packing-cups secured on the stem, the stem immediately above the plunger being grooved spirally, and a glass valve-disk movable vertically on said spirally grooved stem and adapted to be rotated thereon by upward flow of water through the gro'ves, substantially as shown and described.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
